Project

Idea

The VLC positioning system will employ multiple LED’s and a single photodetector in order to calculate the position of the receiver. Approximately 4 LED’s are to be mounted on the roof of a previously prepared small enclosed space. The LED’s used in this design will be of wide field of view (FOV) of around 120°. Such wide FOV is necessary in order to cover the area at hand fully. The LED’s will be placed at known and measured distances and angles relative to each other. Different signals will then be projected by the LED’s throughout the room at intermittent times and the signals will be of isometric forms moving through space as a hemisphere. By developing algorithms to calculate the distance between the source and receiver, one can calculate the exact position of the photodetector. Although the LED’s are crucial to this design, relatively low power LED’s will be chosen for this design in order to increase cost efficiency and make it a plausible option for consumers.

The

Team

Five highly technical undergraduate students will present the whole student body of the team. The team works hand in hand to complete all tasks necessary for the senior design project. All members are proud Texas A&M Aggies who strive to work on a product that will enhance the quality of positioning systems in an efficient and cost friendly manner.
